2 Claims.

My invention relates to circulars, folders, pamphlets, broadsides and similar items, especially for advertising, which are usually Widely 4distributed in various Ways including the mails. Such an item, referred to herein as a folderj ordinarily incorporates printed material on a sheet of paper which is folded one or more times for convenience in handling, and often incorporates some sort of a separate return card or identioation card, or sometimes incorporates as an integral part a return [card which must be detached. Folders incorporating separate cards or separate sheets of any nature are sometimes sealed or held in closed position by an ladhesive mailing stamp binding opposite edges together; but in instances wherein the folders are not to be mail-ed this sealing expedient is not appro- `priate and under any circumstances entails a large amount of labor. Furthermore, Where separate return lor identifying cards are to be included With the folder, they must be fastened in some fashion in order not to be dislodged during handling.

It is 4an object of my invention to provide a folder which can be readily sealed, with a minimum of labor and expense.

Another object of my invention is to provide a folder with which a separate card can be incorporated, but Without the possibility of dislodgment of the card.

An additional object of my invention is to provide a folder having the above-mentioned attributes, which can readily be fabricated in and With existing facilities.

Another object of my invention is in gener-a1 to improve folders.

The foregoing and other objects are -attained in the embodiment of the invention illustrated in the drawing, in which Fig. 1 is a perspective of "a folder fabricated in accordance with my invention, shown in sealed or closed position;

Fig. 2 is a perspective of the folder illustrated in Fig. 1 but in unsealed or open position; and

Fig. 3 is .a cross-section the plane ;of which is indicated by the line 3-3 of Fig. 1.

In its preferred form, the folder of my invention includes a card around which a sheet of paper is folded in ysuch a way as to place the edges of the .paper sheet in registry With an edge of the card, in which :position the parts :are held by a film of adhesive m-aterial applied to the mentioned edges in registry.

The adaptability of the folder of my invention is so Widespread as to present a large number of possibilities for embodiment, but an exemplary embodiment is disclosed herein in which there is provided a paper sheet 6, usually of relatively light, exible stock (which is imprinted on one or both faces with any desired editorial matter. When so prepared, the sheet 6 is reduced into an appropriate compass for lhandling by being folded along a fold line 'I which brings the lateral edges 8 and 9 of the sheet substantially into registry; 'and in order still further to reduce the compass of the sheet it is again folded along a fold line II so that edges I2, I3, I and I5 are substantially in registry and in parallelism, or substantially so, with the fold line II. In the event it is not feasible to secure accurate registry simply .by folding, the edges are trimmed after folding so that their registry is exact. In either case, with such 1a fold the entire sheet can readily be unfolded and spread flat for quick perusal of the editorial matter thereon.

In accor-dance with my invention, I provide in .connection with and protected by the sheet 6, a return or identifying card I8 preferably constructed of relatively stiif material, so that when incorporated :between the folds :of the sheet E, for example between the folds bounded by the line l, the stiffness of the cardV I8 is imparted to the folded sheet and facilitates its handling. The .card I8 is positioned Within the fold in such a way that its edge I9 is immediately juxtaposed to and in registry With the edges I2 and I3 as Well as with the edges I4 and I 5.

In order to secure the sheet and the card in this desired relationship, in a Way suiiiciently permanent to permit of all ordinary handling and also to permit of mailing, yet in such a fashion as not unduly to add to the expense of the folder or to hamper its ready opening, I preferably place along the juxtaposed edges of the card I8 and adjacent sheets an :adhesive material 2l in the form Iof a somewhat flexible film extending at least partially along the edges I2 and 3, for example, and preferably along the entire edge I9.

The adhesive material preferred is of the type commercially known as padding compounds, which can readily be applied with mechanisms now in existence and which has the property of reasonably well relating the various sheet and card edges together for ordinary use; yet when the sheets are pulled apart by :a user, the padding severs, either from the sheet itself or itself divides, `and permits the folded sheet 6 to be readi-ly opened. At the Isame time, since there is no force immediately impressed thereon, the remainquent use or return. Y'

Iclaim: 1. A folder :comprising a paper sheet folded along a line of fold to bring its free .edges into registry parallel to said line of fold, a relatively stiif second sheet overlying part of said ,paper sheet With an edge dispo-sed between and in registry with said free edges, and an vadhesive film applied to all of said edges.

2. A folder comprising a paper sheet folded along a line of fold to bring its free edges into registry parallel to said line of fold, fa second sheet overlying part of said .paper sheet with an edge disposed between and in registry With said free edges, and an adhesive lm lapplied to all of said edges.
